Answer:

y = -2

Step-by-step explanation:

The line that is perpendicular to y-axis will be a horizontal line so it's slope is 0 => y = 0x + b or y = b

Using (5,-2) => -2 = b => b = -2

then y = -2

What is the image of the point (0, 9) after a rotation 90° clockwise about the origin?
yulyashka [42]
<h2>Answer:</h2>

\boxed{A'(9,0)}

<h2>Step-by-step explanation:</h2>

When we rotate a point we could rotate it in Clockwise direction because that's how the hand of a clock move, or rotate it in Counterclockwise direction that's the opposite rotation. In math, counterclockwise is defined as being a positive rotation while clockwise is defined as being a negative rotation.

On the coordinate plane, consider the point (x,y). To rotate this point by 90° around the origin in clockwise direction, you can always swap the x- and y-coordinates and then multiply the new x-coordinate by -1. In a mathematical language this is as follows:

(x,y)\rightarrow(y,-x)

So:

A(0, 9) \rightarrow A'(9,0)

Finally, the new point is:

\boxed{A'(9,0)}

tester [92]

Answer:

The answer would be  the first equation, 6(100)+ 6(5)

Step-by-step explanation:

this is an example of the distributive property of multiplication, meaning you separate the larger factor to make the problem easier, in this case its already seperated for you so you have to add the together, 100+5 is 105 and 6(100)+ 6(5) is equal to 6 x 105.
